4.1 Preliminary checks
First ignition is carried out by competent personnel from an authorised Technical Assistance
Service Beretta. Before starting up the boiler, check:
- that the data of the supply networks (electricity, water, gas) correspond to the label data
- that the extraction pipes of the ue gases and the air suction pipes are working correctly
- that conditions for regular maintenance are guaranteed if the boiler is placed inside or
between items of furniture
- the seal of the fuel adduction system
- that the fuel ow rate corresponds to values required by the boiler
- that the fuel supply system is sized to provide the correct ow rate to the boiler, and that
it has all the safety and control devices required by current regulations
